How many Tome pages are there?
A full count is not published. Pages 12 and 13 are the numbered pair public notes agree on, and that location is Unverified. Slots 1–18 belong to the diamond-grid chest, not to a page index.
At A Glance
The MONOMOON Tome is the knowledge book. Its pages record the roll, show symbols and numbers, hold pictures of places and creatures, and store the rules red doors and the music clam ask you to apply.

| Pages 12 and 13 | Unverified: far-right path to the rightmost telescope |
| Diamond-grid chest | Symbols into slots 1–18. “Fourth Tome chest” is a public lead, Unverified |
| Odd mark | Same border, one symbol in the wrong place — read it, do not “fix” it |

How do I read a MONOMOON Tome page?
The first open often shows an unknown script. Save a picture of that spread in the room, then keep exploring. A single glyph is not a translation, and forcing a digit onto an unread page invents a code the book has not given you.
A page can be early and still useless
A clue can sit in the book before you can act on it. Pictures in a room may stay locked while the page already describes them. Leave that leaf in your notes and come back after the next moon trick or the next collected page. The areas map is where those locked rooms live; this page stays on the book.
What do Tome pages record?
Each leaf is a record of a rule you have earned, not a bestiary entry and not a combat upgrade. Sort a new page into one of the jobs below before you carry it to a door.
| Job | What you should do with it |
|---|---|
| Move | The roll is written down because a gap can be a roll you have not tried |
| Symbol | Match the mark on a red door before you count lines or press a code |
| Number | A symbol can stand for a digit. The swamp elevator reads those digits from the map |
| Music | Note direction follows the scroll’s upright face. The page states the extra rule |
| Picture | A place, a building, or a creature. Use it as a location hint |
| Late hint | Some leaves only make sense after earlier pages exist |
Symbols feed doors and the elevator
Red doors and the music clam both point back at these pages. Symbol pairs, line crossings, digit segments, and triangle dots are solved on the puzzles guide. This book tells you which mark is in play. It does not print a crowned answer. Public line-counts of 6 and 16 are both still in circulation, so a Tome page that shows a crossing is a prompt to count, not a license to type either total.
Music pages explain direction
The underwater clam uses four parts, two notes on each part, cracks for the join, and a rotation. The Tome page is the extra rule: read each note in the direction the scroll is upright. Assemble the clam on the puzzles page after that rule is in the book. If the notes disagree with the cracks, rotate the part. Do not rewrite the page.
Where are Tome pages 12 and 13?
Public notes are the only source for this pair, so the location stays Unverified until a captured page shows the numbers. Those notes put pages 12 and 13 on the far-right path that leads to the rightmost telescope. A blank 12 or 13 means you have not walked that path.
There is no published total. The diamond grid’s slots run from 1 to 18, and that range is not a promise of 18 leaves. Numbered pages and numbered chest slots are different lists. Copying “18” into a page tracker will invent missing leaves that may not exist.
The far-right path is a landmark, not a zone name
Gentle Giant has not published district names. “Far right” and “rightmost telescope” are descriptions. The same side of the map is where hotfix 1.0.08 changed a spot players had called a softlock. If you are on that path and a door will not open, check the areas page for the right-side layout change, then come back here for the leaf. Three observatories do not, by themselves, prove pages 12 and 13 are already in the book.
A late leaf can gate an earlier door
Red-door work in the lower right, including rabbit marks and the tower, has stalled players who already had three observatories. The telescope pages are one lead for that stall. They are not a guarantee that a fourth observatory is the only missing key. If the symbol on the door is absent from your book, stop and walk the far-right path before you reload an older checkpoint. The chest that consumes those symbols is next.
How do I fill the diamond-grid Tome chest?
Public notes describe a diamond-grid chest that wants symbols in slots 1 through 18, and they call it a possible fourth Tome chest. Confirm both claims on the page in your game. The table below is the decision, not a filled solution.
| Situation | Action |
|---|---|
| Two pages share a border, one symbol sits off the pattern | That odd mark is the clue. Place it. Do not “correct” it to match the border |
| The grid asks for slots 1–18 | Fill from your own pages. Recheck any slot you copied from a thread |
| Someone calls it the fourth Tome chest | Treat the count as Unverified until your book shows the earlier chests |
| The script is still unknown | Screenshot, leave, and return after a later reveal |
| A red door wants a symbol you have never seen | Stop. Collect the page. Solve the door on the puzzles guide |
| Notes on a clam part point two ways | Read the music page with the scroll upright, then rotate the part |
| You are about to type 6 or 16 because a thread said so | Count the crossings yourself. This chest page does not crown either total |
Borders are the comparison, not the answer
A repeated frame is how you notice the symbol that does not belong. Line the pages up, mark the intruder, and carry that mark to the slot the page highlights. If every symbol sits where the border says it should, you are on the wrong pair of leaves or you have not revealed hidden text on one of them.
Do not merge the chest with the red-door puzzles
Line crossings, symbol pairs that look like an equals sign, seven-segment digits, triangle dots, and a later four-digit pull are door puzzles. They belong on the puzzles guide. The diamond grid is a Tome chest. Mixing a door total into slots 1–18 fills the chest with someone else’s answer. Screenshot the pages you actually used, which is the next check.
When should I screenshot a Tome page?
Screenshot the page in the room where you find it, and screenshot it again when hidden text appears. The book is the log. Your shots are how you compare borders after you have left.
- Do01First open: unknown script, full spread, before you turn the page
- Do02After a moon change on that page: the same spread with the new text
- Do03Any leaf whose border matches another leaf: both shots, side by side
- Do04Pages you think are 12 and 13: the number and the path, marked Unverified until the digits are readable
- Do05A chest slot you filled: the page you copied from, so a later reveal can undo a bad slot
Why the second shot matters
Hidden text showed up on a book that already looked complete. The player saved each section and overwrote the blank copy. A tilted mark they hoped was a page number stayed a guess. Your second shot is the one that proves a leaf changed. One shot of the closed book is not a page log.
The achievement reported for this book asks you to reveal pages, not merely to pick them up. A leaf with unread hidden text is the gap a single screenshot will hide. The achievement details are in the last section.
What does the Tome achievement require?
trophieshunter lists the Steam achievement Tome: reveal all pages of the Tome. On November 13, 2026 that third-party overlay showed 0.7% of players. The percentage is a snapshot from that site, not a Steam Web API pull and not a difficulty score from Gentle Giant. The full 15-name list is on the achievements page.
“Reveal” matches pages that gain text after you already hold them. Whether every leaf needs a second reveal is Unverified. Hunt blank leaves, re-open old ones after a moon change, and keep going after credits, because hidden routes stay open. Next: take a symbol you can actually read and use it on a door.
What next
Next: put a readable page symbol on a red door in the puzzles guide.
Far-right path, telescopes, and the right-side layout change: areas.
Where the reveal-all secret sits among the other buckets: achievements.
FAQ
Is the roll only a dodge?
The Tome records the roll because the move has more than one use. A gap that looks like a missing jump is often a roll you have not tried in that gap.
Do I need every page before the first credits?
Unknown. The reported secret is “reveal all pages,” and hidden routes continue after a credits layer. A first ending does not prove the book is finished.
Should I trust a tilted number as the page index?
No. A sideways digit on a revealed page might be a page mark. Until the digit is clearly a number on that leaf, keep the shot and leave your index unchanged.
Where do door answers go?
On the puzzles guide. This page identifies the page, the odd symbol, and the chest slots. It does not crown a line-count or a four-digit code.
